Cheryl found a book at Prospero's Books in Kansas City—Handbook for the Soul by Richard Carlson, Benjamin Shield—a collection of essays by leading "spiritual" thinkers. It's very interesting so far.
About the book:
America's most celebrated spiritual writers offer inspiring words on the state of the soul today. This collection of more than thirty original essays addresses both the importance of caring for and nourishing the soul and the ways in which these individuals tend to their own souls on a day-to-day basis.
